Namaste,
I am trying to use my MTS mblaze netconnect with my Fedora 14. The modeswitching takes place automatically. I don't have to manually use the modeswitch command to switch the mode from storage device to modem.
The problem starts after that. When I allow the network manager to connect to the internet automatically, it shows connected and also assigns an ip address to my computer. It also adds the default nameservers in /etc/resolv.conf but I am not able to ping www.google.com or 8.8.8.8. Then I changed the nameservers to 8.8.8.8 and 8.8.4.4. and tried pinging again. It failed.
Next I tried using wvdial. The device connects, but again I am unable to ping and the modem shuts down automatically after 2 minutes or so.
I starting reading more about this and realized that the wvdial is nothing but a heuristic frontend that uses the chat(08) program. I think writing the chat script should solve my problem, but the problem is that to write the chat script I will need specs of how this particular modem works. The modem is identified as ONDA systems communications device after typing lsusb in the shell and the manufacturer is ZTE. If anyone have access to these specs or if anyone has experience in hacking or reverse-engineering their protocol please help.

As a matter of simple procedure, can you check if the computer gets a working connection to the internet through other means? I used to have a similar problem with Fedora earlier, where browsing to sites worked only with IP addresses, although Ping usually worked from the command line. Also check if it is a routing issue, and if you have a default route set.
I don't think this has much to do with your modem or the chat scripts.
Hi Koustubh,
Can you tell me the no of MTS modem i mean the one I am using is AC 2766 and 2746. Both are working fine on my ubuntu 11.4 machine but not working on my embedded device.
You are trying on fedora so if wvdial is not working means either there is problem with providing paaword username or you might have mention wrong name for device i.e ttyUSB0 or something.
check /dev for as what MTS is mapped. # ls /dev/tty*
In my case its mapped as an ttyUSB0, ttyUSB1, ttyUSB2, ttyUSB3, ttyUSB4
so try changing this location in wvdial also keep the baud rate as 115200
hope this will help you.......
